Abstract

Sympatry and syntopy are rare among congeneric cichlids in the Neotropics. Among Peruvian Amazonian cichlids congeneric syntopy has so far been reported in only 1 case known from a single locality. Based on thorough exploration of a new locality I refute the syntopy of the 2 species involved: Bujurquina robusta (Kullander, 1986) is a mouth-bay species while B. labiosa (Kullander, 1986) is an upland species. I demonstrate the generality of this ecological allotopy with further examples from a second study area including a different set of species.
